and :1. which are secured to a horizontal shaft 24, rotatably mounted in the guides 17. Secured to the shaft 24 is a pinio'ni25, Figs. 1 and 5, which meshes with the teeth of a rack bar 26, therear end of which is pivoted to the lower. end of a love? 27, pivoted by means of a bolt 28, to the frame 1, Fig, 1-, the latter having secured to it an arcuate periphcrally toothed plate 29, adapted to have engagement with a pawl 30, slidably' carried on the lever 27, and adapted to be operated b v a. rod 32, connected to a bell cranklever 31, carried by the lever 27. By swinging the lever 27, the supplemental frame 16' may be raised and lowered. When this is done, the operating bar 12 may be lifted at its rear end from engagement with tliepin 14, theresn 1 ,vlouiental frame.

the rear end of the plow- 5, the following mechanism is provided: Secured upon the upper side of'the transverse portion of the U-shaped fram'e 16, is a stationary pulvcriz ing member 33,'the upper side of which is cmicave and corrugated, see Figs. 3 and 5. Above and cooperating with the member 35, is a. rotary cylindrical pulverizing member 34, the periphery of which is provided with spiral corrugations. The member 3-1 is secured to a horizontal shaft. 135. which is mounted in bearings Ill". each of which. as shown in. l igs. and 6, is held clamped be-' tween nuts 37, mounted on two vertical rods or toward the pulverizing member 33. The Y shaft 35 extends through vertical slots 42, provided in the arms of the frame 16. \Vhen a hard substance, such as a rock, .is discharged by the plow 5, between the members 33 and 34, the springs 41 will yield and permit therotary member 34 to rise so as to let the rock pass from between said members. A vertically movable transverse curved guard 43, may be disposed above the rotary member 34.

For rotating the shaft 35 and the member 34, the shaft 35 has secured to it a sprocket wheel 44, which engages a chain belt 45, mounted on a sprocket wheel 46, which is secured to the shaft 2.

One end of the hub of the carryin wheel 3 is provided with teeth 47, adapted to engage similar teeth, provided on the adjacent end of a clutch sleeve 48, which is longitudinally slidable on and has a feather and groove connection with the shaft 2. A lever 49, pivoted to the frame 1, has a bifurcated forward end, which engages the clutch sleeve 48, whereby the said sleeve is brought into and out of engagement with the carrying wheel 3.

If desired, the axle 2 may be rotated by an engine, not shown, carried by the frame 1, and having a driving shaft 50, Fig. 2, to which is secured a sprocket wheel 51, on which is mounted a chain belt 52, which also engages a sprocket wheel 53, which is secured to the shaft 2.

The shaftZhas'pivoted onits left end a lever r54, on one end of which is rotatably mounted a carrying wheel 55,v the other end of the lever being pivotally connected to a rearwardly extending bar 56, having its rear end provided on the lower edge with notches 57, adapted to engage with a transverse pin 58, the ends of which are mounted in the arms of the U-sha wed bracket 15. By lifting the rear end 0 the bar 56, so as to clear the pin 53, said bar may be moved lengthwise so as to swing the lever 54, and thereby raise or lower the adjacent end of the axle 2.

A steering carrying wheel 59. is mounted in a frame 60, which is pivoted at its forward end to a vertical bolt 61, mounted in the frame 1. In the frame (30, Fig. 2, is mounted a vertical rotary shaft (32, to which is secured a pinion 63, which engages the teeth of a horizontal segmental gear 64,

which is secured to the frame 1. Secured to the shaft 62, is a hand wheel 65, by means of which an operator, sitting on a seat 66, carried by "the frame 60, may turn the shaft 62 so as to steer the machine.

At the rear of the pulverizing mechanism is a scraper 67, which is disposed obliquely to the line of travel and is adapted to follow in the furrow 4, and force dirt, which has been dropped therein by the pulverizing mechanism, to one side of the furrow. The scraper 67 is secured to the lower ends of two upwardly extending bars 68, provided adjacent to their upper ends-With vertical slots 69, in which are slidably mounted bolts 70, mounted in the frame 1, and having mounted thereon clamping nuts 70 b means of which the bars 68 may be held ii the positions to which they may be adjusted Secured to the axle 2, is a sprocket wheel 71, to which is connected a chain belt 72, Fig. 1, which is mounted on a sprocket wheel 73, secured to the operating shaft 7-1,of a seed planting device 75, which is mounted on a bracket 76, secured to the frame 1, and

having rotatably mounted on it a carrying wheel 77.

A horizontally U-shaped member 78, Fig.

3, has its arms pivoted to the sides of the plow 5, and supporting a horizontal bar 79, on which are rotatably mounted disk cutters 80, which are disposed and cut the dirt in front of the plow 5. A yoke 81, secured to the arms of the member 78, is provided with an extension 82, which is secured to the link 8, for supporting the member 78.

In operating my invention, the frame 1 is drawn forwardly, with the plow, pulverizing mechanism, and scraper 67, lowered to the position shown in Fig. 3. The low 5 outs i1" continuous furrow slice and ischarges it directly from its rear end, between the pulverizing members 33 and 34, by means. of which the earth is finely pulverized and is discharged, to a large extent, to the right of the furrow which is cut by the plQW,owin

to the spiral arrangement of the periphera corrugations of the member 34. Such earth and described in my aforesaid patent, 'is" eliminated. t

In my present invention the pulverizmg mechanism is much simplified and is located in a low position, and is so disposed that the ice plow alone may discharge its dirt directly between the pulverizing members, thereby eliminating the complicated elevating mech anism and much reducing the cost of manufacturing the machine and the power required to operate it.
